My possibilities for members, take whoever you think fits:
— Porphyria Dempsey, 30, spinster, def loudly ~eschews the norms of society, less obviously academic... but is still a former Ravenclaw into pursuit of knowledge and weird rites and macabre things so might still Vibe.
— Carmelina Cramming, 38, married & widowed, good for runes and ancient curses.
